Discussion: Local advice

I'm coming across to NZ for QB3 and plan to spend a couple of days beforehand in the north end of the South Island (one of the corners of NZ I haven't really been to, apart from heading straight down the road to Christchurch from Picton) - flying into Nelson Wednesday evening and then going across to Wellington Friday evening.

Any local advice would be appreciated - both in the things to see department, and good runs which aren't too extreme (given that I'll be racing on the weekend and don't want to wipe myself out totally).
